The poorly known Sabzevar–Torbat-e-Heydarieh ophiolite belt (STOB) covers a large region in NE Iran, over 400km E-W and almost 200km N-S. The Sabzevar mantle sequence includes harzburgite, lherzolite, dunite and chromitite. Spinel Cr# (100Cr/(Cr+Al)) in harzburgites and lherzolites ranges from 44 to 47 and 24 to 26 respectively. The crustal sequence of the Sabzevar ophiolite is dominated by supra-subduction...
